Paper Abstract
We demonstrated a high-intensity bowtie-shaped nano-aperture Vertical-cavity surface-emitting laser (VCSEL). A
maximum power of 188μW is achieved from a VCSEL with an 180nm bowtie aperture at a wavelength of 970nm.
Simulation shows the near-field full width at half maximum intensity spot size 20nm away from the bowtie aperture is
64×66nm2. The peak near-field intensity from the bowtie-aperture VCSEL is estimated to be as high as 47mW/μm2. This
intensity is high enough to realize near-field optical data storage and the small spot size corresponds to storage densities
up to 150Gbits/in2.
